Abstract

A process for directly growing one-dimension nano-ZnO on CuZn-alloy substrate (such as nanowires, nanobands, nanoflakes, nanocomb, etc) features that said CuZn-alloy substrate is oxidized in the mixed gas (Ar / O2, Ar / H2O, N2 / O2, or N2 / H2O) at 600-1000 deg.C while the Zn content (5-80%), O2 pressure and reaction temp are controlled.

Description

technical field [0001] The invention relates to a method for directly growing uniform one-dimensional nanomaterials such as ZnO nanowires, nanobelts, nanorods, and nanocombs on the surface of an alloy substrate in a large area by using zinc in a zinc-containing alloy material as a zinc source. Background technique [0002] In recent years, one-dimensional nanostructures (nanotubes, nanowires, nanorods, nanoribbons, and their composite structures) have attracted great interest due to their important scientific value and potential applications. Both theoretical and experimental studies have shown that one-dimensional nanostructured materials have a series of excellent properties, such as high mechanical strength, unique electrical, optical and magnetic properties. Therefore, people are competing to use various technical routes to synthesize various one-dimensional nanostructures with special properties. [0003] ZnO is a self-activated semiconductor material with a bandgap of...
